IMPROVEMENT IN PAVEMENTS.

Specification forming part of Letters Patent No. 144,748, dated November 18, 1873 application filed J one 18, 1873.

To all whom it may concern:

Be it known that I, WILLIAM H. DE VALIN,

of the city and county of Sacramento and State of California, have invented certain new The object of my present invention is to avoid the inconvenience and expense of making brlcks of unusual size and shape, and to construct a cheap and durable pavement of common buildin g-brick.

- To construct a cheap and durable brick pavement, and avoid the expense and inconvenience of making bricks of unusual size and shape, I proceed as follows, reference being had to the accompanying drawings: I use the ordinary building-brick, which can be readily obtained at all times. I first prepare a suitable foundation of sand or other material, on which bricks are laid flat, in the usual way of laying walks, as seen at b. Sufficient sand is then put on to fill the joints and make a light dressing, cwhich may be sprinkled with hot c0a1-tar asphalt, to give steadiness to the top course, which is laid in lateral rows 01, the bricks on their edges. Spaces are left between the rows, which are filled with gravel or coarse sand, or other suitable material, and hot coaltar or asphalt poured on to cement it. The surface is then coated with hot coal-tar or asphalt, and combined with sand or brick-dust,

as at f. The top course may belaidwithbricks I of coal-tar, asphalt, or its equivalent, the said bricks so laid being supported on an under course of bricks or other suitable stable foundation, as herein shown anddescribed.

In testimony whereof I have signed myname to this specification before two subscribing witnesses.
